Most schools for students in kindergarten through high school (K-12) have policies that prohibit students from leaving the school grounds or campus during school hours. If students do need to leave the campus they will usually be required to be picked up by an adult (age 18 or older) who is on the student’s emergency contact list and who shows identification at the time of pickup.

For a doctor or dentist appointment schools may require a note from the health care provider for the student’s absence to be excused.

In California, K-12 schools typically have policies in place that prevent students from leaving the school grounds during school hours without proper authorization. These policies are designed to ensure the safety and accountability of students. If a student needs to leave campus, for example, for a medical appointment, they are generally required to be picked up by an adult who is at least 18 years old and listed on the student's emergency contact list. The adult must also provide identification upon pickup. Additionally, to have the absence excused for reasons such as a doctor or dentist appointment, schools may require a note from the healthcare provider. These policies are often outlined in the school's student handbook and are enforced to maintain a secure educational environment. While these policies are standard, they may vary slightly by school district, and local school boards have the authority to set specific regulations that align with state education codes.
